COVID-19 challenged medical students in unprecedented ways such as decreased performance on standardized examinations relative to pre-pandemic benchmarks, as well as negative impacts on mental health [17]. These implications leave us pondering whether the damaging effects of COVID-19 further translated to clerkship preparedness and disrupted the future of practicing physicians. Our study demonstrated that the effects of the COVID-19 pandemic had no significant impact on clerkship preparedness in 3rd year medical students at the Kirk Kerkorian School of Medicine. Shelf exam scores did not vary significantly between the COVID and pre-COVID cohorts as well. Furthermore, the COVID cohort had a significantly higher perceived sense of disadvantage compared to the pre-COVID cohort. The COVID cohort rated experiential learning to be more important than didactic lectures in preparation for LIC, while the pre-COVID cohort rated didactic lectures to be more important than experiential learning for LIC preparation.
Perceived sense of disadvantage related to COVID-19
The findings of our study demonstrated significant differences in perceived sense of disadvantage in clerkship preparation in COVID vs pre-COVID cohorts. In the literature, there is evidence of deleterious effects of COVID-19 on medical student wellbeing, resulting in decreased exam performance, inability to study on campus, and paucity of meaningful relationships with their peers and institutional faculty [11]. Most of the clinical preparation in our study’s COVID cohort was in a virtual format with no clinical exposure prior to the start of LIC. Mock patient interviews with standardized patients in this cohort were conducted via an online format which restricted capacity to conduct essential components of a patient interview such as completing a thorough physical exam. In comparison, the pre-COVID cohort experienced in-person clinical preparation. Students in this cohort had the opportunity to conduct in-person interviews and physical exams using standardized patients.
Prior to initiating LIC, the pre-COVID cohort experienced clinical exposure through shadowing residents and the attending physicians at family medicine clinics. In turn, the pre-COVID cohort was able to become accustomed to working with the medical team staff, conversate with real patients, and gain confidence with their plan of care in a medical setting. To our surprise, the pre-COVID cohort did not find pre-clinical, early exposure to the family medicine clinic experience to be significantly useful in preparation of clerkships. In a study of pre-clinical medical students exposed to a pediatric pulmonary clinic, students felt motivated to care for children and felt a sense of team membership even before the start of clerkship [11]. In another study of early-stage medical students with minimal clinical exposure, volunteering at intensive care units during the COVID-19 pandemic significantly fostered resilience and guided career choices. Unfortunately, some participants found the experience difficult to cope with, and felt overwhelmed by this environment [18]. It seems that there are benefits and downfalls of early clinical exposure during the COVID-19 pandemic. Further studies would need to be conducted evaluating pre-clinical exposure during the pandemic.
Didactic lectures vs experiential learning for clerkship preparedness
Didactic learning can be described as textbook education via knowledge obtained from lectures, PBL cases, and web-based medical board exam resources namely, Boards and Beyond, Sketchy, and Pathoma [19]. Experiential learning is more kinesthetic in nature and is knowledge obtained from experiences including gathering a history and physical exam with standardized patients, exploring types of medical equipment, practicing procedures, and working with residents and attending physicians in a hospital or clinic setting. Students of the COVID-cohort rated didactic lectures to be less important when compared to learning through experience in preparation for clinical clerkships. In contrast, the pre-COVID cohort rated didactic lectures to be more important than learning through experience. Both cohorts felt they were unprepared with the use of medical equipment. The COVID-cohort testimonials from our study’s survey seemed to heavily emphasize their disadvantage of missing out on physical exam training due to pandemic related lockdown. In contrast, the majority of the pre-COVID cohort testimonials stated that they were not significantly impacted by COVID-19 in their pre-clinical years. To elaborate, the pre-COVID cohort still had six months of clerkship exposure before they were moved to a modified virtual clerkship, and they instead emphasized that no student is fully prepared for clerkships until they simply begin this transition phase of their training. Some of the pre-COVID cohort students mentioned that one of the most difficult struggles when starting clerkship is navigating the differing EHRs (electronic health record) at hospital and clinic sites. Some clerkship preceptors agree that navigating the EHR may reduce enthusiasm to teach medical students secondary to decreased time interacting with students and they perceive EHR impedes development of student’s critical thinking and clinical integration skills [20]. To add, it has been demonstrated that medical students do not develop self-regulated learning skills during the preclinical stage of their training, and in fact, some skills decrease in both lecture based and problem based learning (PBL) curriculums. Even with implementation of small-group discussions in PBL based medical schools, the quality of implementation in addition to the unique cultural background of students may influence the degree of self-directed learning [21].
NBME shelf exam performance
When comparing shelf exam scores between pre-COVID and COVID cohorts, there were no significant difference between classes in all six subject exams taken: Family Medicine, Internal Medicine, Obstetrics and Gynecology, Pediatrics, Psychiatry, and Surgery. Currently the clerkship schedules at the Kirk Kerkorian School of Medicine are different from most traditional medical schools. More specifically, each subject of shelf exams are taken in succession within an academic week during the middle of LIC. Shelf exams are then taken again at the end of LIC with a similar schedule to the first round of shelves. Final scores are calculated based on a student’s performance compared to the national NBME average of the previous academic year. Students are assigned one of the following scores for each subject exam: fail, pass, high pass, and honors. Both cohorts maintained higher scores than the national average.
Previous studies report advantages for medical students with the LIC model versus block clerkships such as improved integration within the healthcare team, assuming more roles in patient care, and better understanding of the patient-physician dynamic [22, 23]. The LIC model allows students to consider clinical situations in a holistic manner and incorporate differentials seen across all specialties outside of their current rotation. Research has shown students in LIC, or hybrid models perform better than students undergoing block clerkships in knowledge retrieval, clinical skills, and faculty evaluation [6]. More studies comparing shelf exam scores between medical schools with LIC model versus medical schools with block clerkships would need to be conducted to further elucidate the relationship between clerkship models and exam scores. The authors anticipate the 2nd round of shelf scores at the Kirk Kerkorian School of Medicine at UNLV will also be similar between COVID and pre-COVID cohorts.
Grass is Greener Phenomenon
It has been observed that medical students tend to evaluate the importance of resources based on their level of access to them. This presents a challenge to Medical School Curriculum Committees in determining what content should be included or omitted in the academic curriculum on a yearly basis. The authors of this study propose that the phenomenon of this perspective, referred to as the “Grass Is Greener” phenomenon, is characterized by a general sense of inadequacy, and longing for more favorable outcomes if one had access to the resources that another party possesses. No formal definition of this phenomenon has yet been identified in the literature. The COVID-19 pandemic presented a unique set of challenges for medical students, including disruption in traditional in-person education. Our study illustrates the existence of the “Grass is Greener” phenomenon among medical students, in that feelings of unpreparedness for clerkships were prevalent among students regardless of any limitations imposed by COVID-19 mandates. Despite this, students in the COVID cohort did report missing out on opportunities to develop meaningful relationships with their classmates, but there was no statistically significant difference between this cohort and the pre-COVID cohort in terms of reaching out to peers for emotional support or assistance with learning gaps [11]. Furthermore, this phenomenon may have contributed to the lack of significant difference observed between COVID and pre-COVID cohorts in terms of confidence in performing a physical exam, competence in using medical equipment, and confidence in communicating with medical staff.
The authors of this study propose several strategies to mitigate the negative effects of the “Grass is Greener” phenomenon among medical students. One key method is to improve transparency in communication between medical students and faculty, particularly regarding curriculum changes. The authors suggest that when administration makes modifications to the curriculum without seeking input from medical students, it can leave students feeling confused and uncertain. Another strategy is to ensure continuity of resources for current students by maintaining access to materials and resources used by previous cohorts, such as study guides, notes and other learning tools, even after the assessments or requirements for completions have been done. These resources can be useful as an adjunct to the current curriculum and help students feel more prepared.
Recommendations to improve clerkship preparedness
The transition from didactic training to the LIC component of training can be a challenging process for medical students. Exam scores become replaced in part by subjective evaluations completed by residents and attending physicians and require more critical thinking and execution of clinical skills. Kirk Kerkorian School of Medicine at UNLV has attempted to mitigate the difficult shift by implementing a clerkship bootcamp prior to the start of clinical rotations. To elaborate, the bootcamp program is two weeks in duration and features rotating stations involving application of clinical skills, patient interviewing, and exploring high yield topics taught by residents and attending physicians in each of the six subspecialties: Psychiatry, Family Medicine, Pediatrics, Internal Medicine, Obstetrics and Gynecology, and Surgery. Additionally, for two days out of the two-week training period, our medical students had the opportunity to receive comprehensive instruction on the technical and psychosocial components of reproductive and sexual health exams [24]. A similar clinical skills clerkship program at another institution has demonstrated success in preparing students for LIC. In their model, they implemented a similar three-week course that had three major components: 1. A longitudinal clinical care of a three-generation virtual family assessed with an objective structured clinical examination (OSCE), 2. clinical skills stations 3. professional development exercises [25].
